RESEARCH METHODOLOGY

Detailed explanation-1: -A manipulated variable, also known as an independent variable, is a part of an experiment that you can change to see how other variables respond. Here are the three types of variables in an experiment: Manipulated variable: The variable that you control and change based on the experiment.

Detailed explanation-2: -Again, to manipulate an independent variable means to change its level systematically so that different groups of participants are exposed to different levels of that variable, or the same group of participants is exposed to different levels at different times.

Detailed explanation-3: -Independent variables (IV): These are the factors or conditions that you manipulate in an experiment. Your hypothesis is that this variable causes a direct effect on the dependent variable.

Detailed explanation-4: -Researchers often manipulate or measure independent and dependent variables in studies to test cause-and-effect relationships. The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect.

Detailed explanation-5: -Manipulated variable: The number of hours spent studying. This is the variable that the teacher manipulates to see how it affects exam scores. Response variable: The exam scores. This is the variable that changes as a result of the manipulated variable being changed.
